The Haunted is a fast paced thirdperson horror-action game with focus on a intense multiplayer experience that is all about making a stand and liberating cursed places from the minions of evil.
The game features several multiplayer modes such as coop or demons .vs. humans, where enemies are spawned and controlled by players.
The outstanding visuals lay a perfect tone for the gameplay.

Hopefully that will fix my custom keys too. For some reason they always re-set to defaults.
I may have to change the default key in the configuration file
